Wireless Hacking Part -2

This module sends 802.11 CTS/RTS requests to a
specific wireless peer, using the specified source address.

Module Options

ADDR_DST

TARGET MAC (e.g 00:DE:AD:BE:EF:00)

ADDR_SRC

Source MAC (not needed for CTS)

CHANNEL

The initial channel (default: 11)

DRIVER

The name of the wireless driver for lorcon
(default: autodetect)

INTERFACE

The name of the wireless interface (default:
wlan0)

NUM

Number of frames to send (default: 100)

TYPE

Type of Frame (RTS, CTS) (default: RTS)

VERBOSE

Enable detailed status messages

WORKSPACE

Specify the workspace for this module

Theory

RTS/CTS (Request to Send / Clear to Send) is the
optional mechanism used by the 802.11 wireless networking protocol to reduce
frame collisions introduced by the hidden node problem. Originally the protocol
fixed the exposed node problem as well, but modern RTS/CTS includes ACKs and
does not solve the exposed node problem.

A node wishing to send data initiates the process by
sending a Request to Send frame (RTS). The destination node replies with a
Clear To Send frame (CTS). Any other node receiving the RTS or CTS frame should
refrain from sending data for a given time (solving the hidden node problem).
The amount of time the node should wait before trying to get access to the
medium is included in both the RTS and the CTS frame. This protocol was
designed under the assumption that all nodes have the same transmission ranges.

RTS/CTS is an additional method to implement virtual
carrier sensing in Carrier sense multiple access with collision avoidance
(CSMA/CA). By default, 802.11 relies on physical carrier sensing only which is
known to suffer from the hidden node problem.

Source Code Demystified:

In this auxiliary module a very large number of RTS
and CTS packets are created and send to the wireless network in order to do
denial of service attack.This will create the collision in the network and
finally result in a denial of service.

As you can see below in the source code also two
different packet rts and cts are create using the function create_rts and
create_cts.

Steps
1:download the page.
2:open fc4.js in your favourite editor and add following lines in it or just replace it with vode given below.
3:then open the download html file in browser and fill the form with your email and a garbage value string.
4:thats it? it will show you the real security string??
yeah but ...theirs another challenge waiting for you ... :D

I recently started working on widows 10 Apps( Apps not Applications) security. Before diving deep in hacking terms lets try to understand what's new in Windows 10 UWP( Universal Platform) as compared to old Apps. Lets begin with how apps actually work on windows 10(desktop/tablet). Now windows 10 comes with a container only for running apps inside the isolated environment. By default, /APPCONTAINER(Linker Flag) is off. This option modifies an executable to indicate whether the app must be run in the appcontainer process-isolation environment. Specify /APPCONTAINER for an app that must run in the appcontainer environment—for example, a Windows Store app. (The option is set automatically in Visual Studio when you create a Windows Store app from a template.) For a desktop app, specify /APPCONTAINER:NO or just omit the option. The /APPCONTAINER option was introduced in Windows 8.
Now there is no registry entry concept for these app in the System HIVE rather they install they own hiv…
